Ontario's Windmills

Two days a go the government decided to delay authorizing building wind farms (group of windmills in an area used to generate electric power) in the Great Lakes. It seams a group of citizens in the Scarborough area are raising health concerns. The concerns are that the windmills will bring up toxins in the water and pollute our drinking water.Are they overacting I don't know. But we need to consider the possible health risk to Ontario's residents. In a article in The Globe and Mail by Marcus Gee he raises the point that dredgers( a powerful machine that digs up earth from beneath rivers) have been used in the harbours of Lake Ontario and they haven't stirred up dangerous toxins, so why would the windmills? Even though the decision has been delayed the the general belief is that the windmills are a safe green way to produce energy.
